Application tiled October 21, 1912. Serial No. 728,950,

To all whom z't may concern.'

e it known that I, AUGUST KADow, a citizen of the United States, residin at Toledo, in the county of Lucas and tate of Ohio, have invented certain new and useful Improvements in Glass-Article Discharge and Cut-Oft" Mechanism, of which the following is a specification. 1

My invention `relates to machinery manufacturing glass articles.

One of the objects of the invention is to provide an automatically operating apparatus for removing from a glass forming machine the glass blanks or articles madcby said machine, and for transporting the same to some convenient point of deposit.

A further object is to provide apparatus for cutting off or otherwise removing the surplus glass from said blanks or articles. l More' specifically, the object of the pres-- ent invention is to provide apparatus, which will operate automatically in connection with the machine for making electric light bulbsshown in my pending application Serial No. 570,621 filed July 6, 1910, for receiving the bulbs as they are discharged from the spindles and for transporting the same to any desired point for inspection and packing; and, further, to provide means, operating in connection with said receiving or take off device,'for removing the surplus glass at the stem or neck of the bulbs, namely, those portions of the blanks which arc held by the spindles during the blowing operation and preferably before cooling.

The invention consistsin certain novel constructions, arrangements and devices, to be hereinafter' described and claimed, for effectively and economically carrying out for 1 the purposes above stated.

While the invention will be described in conjunction with the machine of my pending application above referred to, it will be readily understood that the devices which I lay claim to might be used in connection with other machines of similar y character.

Like characters of reference designatelike parts in the several figures of the drawings. The apjiaratus which forms the subject matter of this application is illustrated and will be described, as stated, in connection with the machine for forming electric light bulbs shown in my pending application This machine comprises a base 5G, a stationary drum on said base, the lower section of which is designated 5l, and a framework, a portion of which is shown in the drawings herein and designated 52, which framework rotates around the upper section 53 of the stationary drum. The framework 52 carries a number of glass forming units each of which units is capable of turning out bulbs completely made so far as the operations of this machine areconcerned. Each unit comprises, among other instrumentalities which do not concern the present invention, a spindle 54 provided with jaws 55 (Fig. 27) which hold the neck portion 56 of the blank durin the operation required for forming the bu b. Each unit comprises also a Vfinishing mold 57, consist-4 ing of two mold sections hinged together within which the. bulb is rotated, by the axial revolution of the spindle, this operation being the nalstep in the series ofoperaq tions performed by the glass forming machine in question. At the conclusion of this finishing operation the mold opens and is moved out of the vicinity of. the bulb. Shortly thereafter the jaws 55 of the spindle are opened to discharge the blank.

My present invention provides means for cutting, grooving or otherwise weakening the neck ofthe bulb betweenv the portion inclosed in the mold and that held by the spindie jaws by an operation which takes place during the rotation of the bulb in the finishingmold.

he invention provides further, a rotary takeoff device which is located near the machine and is provided with jaws which grasp the blb just as 'it is released by the opening ol' th spindle jaws. With this take-a' device is associated a hammer which, at the proper moment, strikes and knocks oil the surplus glass from the bulb, namely, the upper portion of the neck of the bulb beyond the groove or line of weakness produced, as above described, while the blank is in the mold. The jaws on the takeoff device are opened at the time the bulb is brought over a receiving chute, the bulb being first tilted to a proper angle to minimize the dii-nger' ol' breakage when it strikes the chute, and the bulb is thereupon discharged into the chute and directed. to a conveyer operating to transport the finished bulbs to the pro er point in the factory for inspection and shipnient.

The groaning knife. See particularly Figs. l, 3, 27 to 33 inclusive.)-Seciired to the base 50 is a bracket 58. The knife, pref'- crably' made in two sections, 59, 59a, is mounted on the bracket so as to be adjustable horizontally and vertically and so that, when occasion demands, it may be quickly thrown out of its operative position. The arrangements for accomplishing these ends are follows: 60 designates a curved plate secured in a groove 61 formed in the face of a vertically movable slide G2 which latter is mounted onthe horizontally movable slide 68 on the bracket 58. The knife sections are formed with slots 64 for Athe set screws 65. The knife sections back u against set screws threaded through split collars 67 on the plate 60 which are tightened by screws 68. This arrangement gives horizontal adjustability to the knife.

The vertical slide G2 is movablygmounted in guideways 69 formed in an upstanding web 70 on the horizontal slide 63. The desired vertical position of the knife may be obtained by the adjusting screw 71 which passes through a lug 72 on the vertical slide and a lug 73 on the web 70. The horizontal slide (i3 is movably mounted in uideways 74 provided in the upper end `of the bracket 58. Pivotally mounted on a pin 75 on the under side of the bracket is a bell crank lever 76 having a'hand grip 77, the short end of the bell crank being connected by means of a link 78 to a block 79 adjustab-ly mounted in guideways 80 in the slide 63 and secured thereto by the adjustin screw 81. A spiral spring 82 is interpose between lugs 83, 84E formed on, respectively, the block 79 and the bracket 58. The adjusting screw 81 'which passes loosely through an lopening in the slide 63 and is held against movement' lengthwise by the collars threaded opening 86 in the to adjust the tension of the spring 82. A set screw 87 is arranged in the bracket in o sition to stop the bell crank ever 76, with the centers of pivot ins 88, 8 of the link 78 out of line with tie center of bell crank pivot pin 75. With the positions shown in Fig.

block 79, serves 81the knife is dis` and enters aparts in the relative posed in the path of the blank, that is, in the position shown in Fig. 27. By throwing the handle'77 of the bell crank to the left (Figs. 1, 28 and 31) the slide (i3 is drawn backward on the bracket so as to move the knife out of its operative position.

With the knife in the operative position the blank is brought against it duringl tbc period in which the blank is iuclosed in the mold. The mold has a rotary movement as it is secured to the rotary frame 52 of the glass forming machine. T hc blank is thereore carried along the edge of the knife at the same time it is rotated. This forms the circumferential groove 90 in the blank shown in Figs. 11 and 27. The knife sections 59, 59 are preferably arranged eccentrically with respect to the 'axis of the machine, the extremity of knife section 59 adjacent the section 59l being a. trifie closer' to the axis of themachine than the other end of this section of the knife. ln this way. as the blank travels along the edge of knife section 59 the groove is gradually deepened. Similarly the knife section 59L may be arranged so that there is a gradual separation of the blank from the knife. The chief function of the knife scction 59 is to keep the groove or cnt open until the glass has a chance to congcal. The eccentric arrangement of the knife sections is so `slight that no attempt has been made to illustrate it in the drawings.

T/zc talco/f dcrzcc-gcnercl construcirm.-'I`he take-oil` device is preferably connected with the glass forming machine so that it may be adjusted on a curved line concentric with the axis of the machine. It consists of a rotary framework preferably driven from the glass forming machine, which carries one or more take-oli'1 units operated by certain stationary cams.

Referring to the drawings, particularly Figs. 1, 3, 0, 7, 2l and 34, 91 designates a bracket which is secured to the lower section 51 of the stationary drum ol' thc`machine and is provided with a curved portion 92 concentric with the axis of thc machine. The operative parts ol the take-off device are mounted on a pedestal 93 having' a base 94 secured by means of the bolts 9? to adjusting gnideways 00 formed in thc curved portion 92 of the bracket. Supported in the` pedestal 9? is a sha ft 0T held in place by collars 98. -llolalably mounted on the shaft 97 is a. circular platcll.) formell with the extension plates 100 on which tbc mechanisms for removing.lr the blanks from the spindles and for lmocking offl the stem portions thereof are located. The machine shown in the. ('lrawings has tyvo sets of these mechanisms. Fixed to c upper end of the shaft 97 is a spider 101 supporting certain cams for alctuaii g themovcmcn'ts of the take-olf mechanism.

The talee-07?' device-drive and dutch. (See particularlyj Figs. 3, 5 7, 9, 2l, 24- and 25.)-l-The mechanism for driving the takeo device from the glass forming machinewhich mechanism, it will be understood,has to bc adjustable to accommodate itself to the adjustment of the position of the takeoff device with respect to the machine-s preferably made -np of the following de' vices:

The rotating frame 52 of the glass forming machine carries a circular rack or gear 102 by means of which the frame is given its rotary movement. The take-off device, in the embodiment thereof shown in the drawings herein, is 'driven from the rack 102.

103 designates a, countershaft jonrnaled in a. bearing 104 in a housing 105 on the base 50 of the glass forming machine. Fixed to the upper end of the countershaft 103 is a gear wheel 10G meshing with the circular rack 102. The other end of the countershaft 103 carries a bevel pinion 107 which is mcshed with a bevel pinion 108 on the end of a two-part extensible shaft 109, 110. The other end of the. latter shaft carries a bevel pinion 111 meshing with a pinion 112 on a vertical shaft 113 journaled in a bearing member 114 carried by a bracket 115 on the base member 94. On the upper end of the shaft 113 is a gear wheel 116 which meshes with a large gear wheel or circular rack 117 secured to the under side of the 'plate 99. The outer section 110 of the transmission shaft is provided with a socket 118 which receives the end of the other section 109, the latter being formed with a slot 119 into which projects a key 120 in` a collar 121 secured adjustably to a collar 122 on' the socket member 118 by means of bolts 121*1 which pass through curved slots i121 in 'a fiange 121c on the collar 121. This adjustablity allows the bevel pinions 108, 111 to be set so that they will properly mesh with the pinions 107, 112, respectively. The section 109 of the transmission shaft is journaled in a bearing member 123 which is loosely mounted on thc cylindrical portion 124 `of the bea ri ng member 104, the shaft 109 being provided with a collar 109 pinned thereto and bearing against member 123. Similarly the other section 110'of the transmission shaft is journaled in a bearing member rotation of the framework 52, driven bythe rack 102 as shown in myA said co-pending iso Y portion of the take-olf device.

application, and since the take-oli' jaws are also actuaixed from rack 102, these two mechanisms may be synchronized so Vthat when the spindle rele-ases the blank it will be seized in 'the jaws of the takeoff mechanism.

The gear 116 is loosely mounted on the shaft 1,13 and is clutched thereto by the following mechanism: The lower face of the gear 116 is formed with the semieircular clutching element 127 adapted to engage with a slmilarly formed element 128 on the clutch member 129, the latter being' feathered to and slidable upon the shaft 113. The clutch member 129 is raised and lowered by means'bf a bell crank 130, one end of which is formed with the yoke 131 provided with pins 132 which extend into a circumferential groove 133 in the clutch member. he bell crank; is mounted on a pivot Stud 134 fixed in e boss 135 on the pedestal 93. The arm 136 of the bell crank provided with a pin 137 adapted to be engaged by the cam 'face 138 (Fig. 24) one cum rod 139'slidably mounted in a boss 140 on the base member 94. The cam rod is moved back and forth by a hand lever 141 pivoted to the rod 139 and to arod 142 which carries a yoke 14B pivoted to lugs 144 on thesboss 1.40. The movement of the cam rod 139 is limited by a pin 139" in the rod which projects into a slot 140 in the boss 140. The clutch member 129 is normally kept in engagement with the pinion 116 by means of a spring 145 seated on the upper end of the bearing member 114. This spring is compressed when the cam rod 169 is drawn out and thebell crank 130 rocked to move the clutch member out of engagement with the pinion.

The yblc/rdc manipulating devices. (See particularly Figs. 3 to 8, inclusive, 10 to 17- inclusive, 20 and 26. The bulbs are grasped and removed from the glass forming machine, this operation taking place exactly at the moments when the spindle jaws open to release the blanks, by means of automatically operating jaws carried by the rotating These jaws comprise a pair of arms 146 (Fig. 11), the forward edges of which are' curved and V- shaped in cross section as indicated at 147, these edges being preferably adapted to enter the groove 90 in the blank; and of arms 148 (Fig. 12) having curved portions 149, the interior surfaces of which are smooth so as to engage the cylindrical stem 150 of the blank as is best shown 1n Figs. 14 and 15. The arms 146, 148 are formed with the which enter guideways 153, 154 in blocks 155 which form part of the lever arms 156, 156, the jaw arm extensions'll, 152 being held in place in the guideways by ymeans of the set screws 157 which pass through slots 158, 159, respectively, 1n the' extensions 151, 152. The lever arms 1.56, 1.56 are pivoted by means of the studs 160 to a revoluble member 161 (Fig. 1.7). 'The inner ends of the lever arms 156, 156 are rovided with studs 162 which fit into note es 163 in semicylindrical slides 164 (Fig. 26) which fit into bosses 165-on the rocking member 161 and are provided with stems 166 passing through openings in the ends of sleeves 167 (Fig. 16) secured to and projected into a housing 168 secured by a bolt 169 to thc projection 100 formed on the plate 99 (Figs. 14 and 15). Extending over the top of the housing 168 is a slide 170 provided with inturned flan es 171 which extend into uide slots 172 in the sides of the housing. ounted on a stud 17 3 on the top of the slide 170 is a roller 174 which, at a certain point in the rotation of the plate 99, meets a cam 175 (Fig. 5) which consists of a projection or widened portion of a ring 176. This cam ring is mounted in a groove formed in the outer ring 177 of the spider 101. The slide 170 is formed with the vertical iiangcs'178 which abut against rocking members 179 (Figs. 6 and 20) which are pivoted on studs 180 to formed on the sides of the housing 168. The rocking members 179 are provided with yokes 182 which bear against washers 183 that in turn bear against nuts 184 on the threaded extremities of the stems 166 of the slides 164. Surrounding the stems 166 are spiral springs 185. A spiral spring 186 is interposed between a lug 187 at the back of the -slide 170 (Figs. 14, 15 and 20) and a spring ocket 188 :formed on the under side of a. sli e 189, the latter being normally held against movement in the direction in which the pressure of spring 186 is exerted. The outward movement o the slide 170, which occurs when the roller 174 meets the cam 175, causes the slides 164 to move in opposite directions against the' tension of springs 185 which rocks the lever arms 156, 156 so as to open the jaws. When the roller 174 leaves the cam 175 the jaws close. Preferably the roller is held slightly out oi' contact with the narrow ortion of the ring by a stud 168'L on the ou'sing 168 against which the back of slide 170 abuts.

The blank is receivedby the jaws of the takeoff device in a vertical position (Fig. 14). It is afterward turned into a horlzontal position (Fig. 15) in order that the stem portion 56 beyond the notch 90 may bemore conveniently knocked 0H." l

he mechanism for swinging the jaws so as to turn the blank from one position to the other is made up of the following parts:

he bosses 165 on the revoluble member 161 are formed with teeth 190 which are meshed by racks 191 on the under side of the slide 189 before mentioned. Secured to this slide by the screws 192-is a plate 198 formed with a projection 194 carrying a stud 195 on` projections 181
